Troffer lighting (aka recessed troffer lighting) is a term that is often used to describe indoor lighting fixtures that are mounted within a ceiling or ceiling grid, hence the term “recessed.” Typical fixture sizes include 1x4 troffers, 2x2 troffers, and 2x4 troffers. This type of interior lighting is located in a range of building types and workplace usage, and is commonly used to provide illumination for commercial lighting, industrial lighting, retail lighting, warehouse lighting, and classroom lighting applications.
Below are a few image examples of troffer lighting applications. The below photos are by no means representative of all the types of 1x4 troffer, 2x2 troffer, and 2x4 troffer applications, they are just a quick visual sample.
